When aluminum cans are formed, they are washed and cleaned. A special coating is also applied inside the can. In the printing machine, up to 6 rollers of different inks provide the colors that cover the printing pages. (Similar process compared to offset lithography). After contact with rubber felt, the can has a complete negative image in any color. This process is considered wet (wet) on wet ink. After passing each color on the rotating belt, the final image is formed and to protect the can / paints from wear and tear, a special coating is applied on each can. The completed cans are sent to an ultraviolet oven that operates at more than 100 degrees Fahrenheit and contains 6 to 8 300 watt UV lamps.Both inside and outside the can are exposed to light to ensure proper cooking of the ink.
